Heosemys grandis
This pair was aquired from a pet store in Ames, Iowa
Really good forum and care site for this species: Heosemys grandis forum
These guys were kept in a large tank with gravel, and this is why I do not keep any turtles on gravel.
These rocks came out of the larger of the two big ones.
These rocks came out of the smaller of the two big ones.
I got 2 more smaller ones from an ad on Turtle Times and this is how they were shipped in 30 degree weather!
